The 17-year NYPD veteran was slapped with charges of criminal obstruction of breathing and assault after the girlfriend claimed there had been a previous, unreported attack, sources said.
The victim declined medical attention at the scene.

The bust represents another black mark in Santiago’s checkered tenure with the department, sources said.

In June 2003, while on active duty as a Marine reservist in California, Santiago was among 20 men involved in the chair-throwing melee outside a Hyatt Hotel in Palm Springs.

He was charged with assault and briefly suspended from the NYPD.

But in 2013, Santiago was lauded for his quick-thinking collar of a teenage shooting suspect outside his precinct’s Morningside Heights station house.

A loaded .380 caliber gun was found on the teen and later tied to the nonfatal shooting of a 22-year-old man.

Santiago’s arraignment for the domestic incident was pending Saturday.
